Reply To: I have an electronic song with a constant beat, at 152bpm, but goes out of sync.
you don’t have to do a tempo marker for every measure. you only need to do tempo markers at the point where the song starts to become out of beat. sometimes that means more markers depending how often the song is not on tempo. however, this is just part of charting and there’s no easy way around it. it takes some time to learn and some skill to have in order to do proper tempo mapping. watch the tutorials, watch some videos, read some of the forum tips and you’ll be okay. but very few songs are perfectly tempo mapped out of the gate (although, a lot of current music seems to be produced, so it’s more likely to find tempo mapped music more frequently now).
